Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65000, here are decompositions:

  • 3 + 64997 = 65000
  • 31 + 64969 = 65000
  • 73 + 64927 = 65000
  • 79 + 64921 = 65000
  • 109 + 64891 = 65000
  • 151 + 64849 = 65000
  • 283 + 64717 = 65000
  • 307 + 64693 = 65000

Showing the first eight; more decompositions exist.
